Introduction

Welcome to the homepage of OpenStego, the free steganography solution.

OpenStego provides two main functionalities:

• Data Hiding: It can hide any data within a cover file (e.g. images).
• Watermarking (beta): Watermarking files (e.g. images) with an invisible signature. It can be used to detect unauthorized file copying.

Please see Concepts page to learn more.
